Aromatase inhibitors (AI) are the standard adjuvant hormone therapy for postmenopausal women with hormone-sensitive breast cancer. However, nearly half of patients experience AI-induced musculoskeletal symptoms (AIMSS), particularly pain, which compromise quality of life and treatment adherence. While adapted physical activity offers proven benefits in oncology, its specific role in preventing or managing AIMSS remains unclear. Moreover, the maintenance of physical activity during the care pathway in real-world settings is limited, highlighting the need for hybrid approaches that evaluate both clinical effectiveness and implementation. In response to these challenges, the primary study aim will be to compare the prevalence of musculoskeletal pain after six months of aromatase inhibitor therapy between patients initiating a personalized adapted physical activity program at the beginning of the care pathway and those receiving usual care. Secondary aims will be to (1) assess additional effects of the intervention on physical health, psychosocial well-being and treatment adherence, (2) explore contextual factors influencing program implementation in routine oncology care and (3) identify potential risk factors for the development of AIMSS. The APIS study is a hybrid type I effectiveness-implementation randomized controlled trial including 182 postmenopausal women with non-metastatic hormone-sensitive breast cancer. APIS will generate new evidence on the clinical and implementation effectiveness of early personalized APA (Adapted Physical Activity) in preventing AIMSS. The hybrid design will support the development of sustainable, patient-centered interventions, potentially improving quality of life, adherence to AI therapy and long-term outcomes in breast cancer survivorship. Ancillary study (Groupement Hospitalier Nord, Hospices Civils de Lyon) The humero-scapulo-thoracic region is particularly exposed to functional alterations during the course of care of patients treated for breast cancer. In addition to the loss of strength and mobility associated with surgical and medical treatment, the shoulder can also be the site of pain due to AIMSS or PMDS (Post-Mastectomy Pain Syndrome). These pains are often studied separately, depending on the treatment, but few studies offer a global vision of the functional evolution of the shoulder throughout the course of care, enabling prevention and adjustment of management. It is also relevant to assume that early APA treatment could improve functional rehabilitation in this area. The aim of this study is therefore to evaluate the impact of an APA assessment and early referral to a personalized program (APIS protocol) on shoulder functionality, depending on the time of intervention in the therapeutic pathway.

Score of most intense musculoskeletal pain
To analyze the impact of implementing a specific APA program, right from the start of treatment, on the prevalence of musculoskeletal pain experienced by patients treated for breast cancer with aromatase inhibitors (AI) after 6 months of hormone therapy (peak of symptoms). Musculoskeletal pain are measured using the Nordic-type questionnaire. This score is measured using the Nordic questionnaire, which includes a Numerical Rating Scale (NRS) for musculoskeletal pain ranging from 0 to 10: * 0 = no pain or discomfort * 10 = intolerable pain or discomfort A higher score reflects a more unfavorable clinical outcome.
Time frame: 6 months after introduction of hormone therapy
Evolution of musculoskeletal pain intensity
Musculoskeletal pain is measuring using the evolution of the score of the Nordic Musculoskeletal Questionnaire. The score was compare between pre-therapy and 6 months of hormone therapy in experimental and control groups. The Nordic Musculoskeletal Questionnaire including a Numerical Rating Scale (range 0 - 10), with higher scores indicating more severe pain.
Time frame: From the initial phase to 6 months after the introduction of Aromatase Inhibitors.
Score of global pain
Global pain is measured using the numerical scale. The numerical scale is a self-assessment scale and consists of asking the patient to quantify her overall pain at the present moment on a virtual scale ranging from 0 (no pain) to 10 (maximum imaginable pain). The aim is to compare the effects of the intervention on overall health outcomes, including physical health and psychosocial well-being.
Time frame: From the initial phase to 6 months after the introduction of Aromatase Inhibitors.
Evaluation of Quality of life
Quality of life is measured using FACT-B (Functional Assessment of Cancer Therapy - Breast) scale associated with the endocrine subscale (ES). FACT-B scale is a validated instrument designed to assess health-related quality of life in patients with breast cancer. It includes 37 items covering five domains: physical well-being, social/family well-being, emotional well-being, functional well-being, and breast cancer-specific concerns. Each item is rated on a 5-point Likert scale ranging from 0 ("not at all") to 4 ("very much"). Scores are summed to yield a total FACT-B score ranging from 0 to 148, with higher scores indicating better quality of life. Endocrine subscale (ES) specifically assesses endocrine symptoms and includes 19 quantifiable items such as hot flushes, weight gain and joint pain. Items are scored using the same 0-4 Likert scale, resulting in a total ES score ranging from 0 to 76, with higher scores reflecting fewer endocrine symptoms and better quality of life.
Time frame: From the initial phase to 6 months after the introduction of Aromatase Inhibitors.
Fatigue
Fatigue is measured using FACIT Fatigue - version 4- (Functional Assessment of Chronic Illness Therapy - Fatigue) Scale. The aim is to compare the effects of the intervention on overall health outcomes, including physical health and psychosocial well-being. Patients respond using a 5-point Likert scale. Each response is scored from 0 ("not at all") to 4 ("very much"). The scoring system reverses the numbers for negative items. This means that for 11 items with negative statements (such as "I feel tired"), a 4 becomes a 0 and a 3 becomes a 1. Adding the 13 scores gives a total between 0 and 52 points. Higher total scores mean less fatigue and a better quality of life. Scores below 30 indicate severe fatigue.
Time frame: From the initial phase to 6 months after the introduction of Aromatase Inhibitors.
Anxiety
Anxiety is measured using HAD (Hospital Anxiety and Depression) scale.The aim is to compare the effects of the intervention on overall health outcomes, including physical health and psychosocial well-being. The HAD scale is a tool used to screen for anxiety and depressive disorders. It consists of 14 items rated from 0 to 3. Seven questions relate to anxiety (total A) and seven others to depression (total D), thus yielding two scores (maximum score for each = 21). Interpretation: To screen for anxiety and depression symptoms, the following interpretation can be used for each score (A and D): * 7 or less: no symptoms * 8 to 10: possible symptoms * 11 or more: definite symptoms.
Time frame: From the initial phase to 6 months after the introduction of Aromatase Inhibitors.
Cognitive complaints
Cognitive complaints are measured using FACT-Cognitive Function -version 3 (Functional Assessment of Cancer Therapy - Cognitive Function) scale. The aim is to compare the effects of the intervention on overall health outcomes, including physical health and psychosocial well-being. The FACT-G comprises four subscales: physical well-being (PWB; 7 items, score range 0-28), social/family well-being (SWB; 7 items, score range 0-28), emotional well-being (EWB; 6 items, score range 0-24), and functional well-being (FWB; 7 items, score range 0-28). Negatively worded items are reverse-scored before summation, so that higher subscale and total scores indicate better self-reported cognitive functioning.
Time frame: From the initial phase to 6 months after the introduction of Aromatase Inhibitors.
Physical condition
Physical condition is measuring using the 6-minute walk test. The score (between 375 and 546) was compare between pre-therapy and 6 months of hormone therapy in experimental and control groups (higher score mean a better outcome).
